Abstract (en)

[origin: WO9306518A1] A wavelength-selective arrangement interacts with optical radiation propagating in a transmission medium (8). The arrangement comprises a selector member (2) made of a polar organic material which exhibits piezoelectric properties, the selector member having an interaction surface for interacting with the radiation. The selector member (2) is provided with means (3, 3a) for propagating surface acoustic waves along the interaction surface (4) so as to create a grating and thereby determine its interacting properties in relation to the wavelength of the radiation, in a selectively variable manner.
